VERY minor issue with upgrade.sh - reverts grafana version ... not ever sure it's a bug - maybe a feature! ;-)

So I was tidying up my Powerwall installation and figured I might as well push to the latest version - I was running 4.5.1. I ran upgrade.sh which works GREAT ... like super-duper brain-dead easy - thank you @jasonacox ! ;-)

I have a couple of customizations dealing with network ports and grafana access ... and upgrade.sh handled those perfectly.

However, a while back I played around with more recent version of grafana (see #371) so I'm using 9.4.17. The upgrade reverted me back to 9.1.2 in powerwall.yml ... which was trivial to fix and I'm all good.

This is obviously a VERY minor issue ... heck, I'm not even sure it's a "bug" ... since arguably a "feature" that upgrade.sh puts you on whatever the current "approved" version of grafana is.

However, I'm wondering if I might make sense to have upgrade.sh generate a message - i.e. something like "V4.6.0 uses grafana 9.1.2, but I see you are running 9.4.17. I have changed that to 9.1.2, but check your configuration/dashboard and if you want to change it, simple update powerwall.yml and restart"

Just tossing it out there for consideration.
